Question

In the reaction, P + Q → R + S The time taken for 75% reaction of P is twice the time taken for 50% reaction of P. The concentration of Q varies with reaction time as shown in the figure. The overall order of the reaction is, 2, 3, 0, 1

MARKS App · Accepted Answer

For P, t 75 % = 2 t 50 % I s t order w.r.t 'P' For Q, Q = Q 0 - kt . i.e. zero order. i.e. overall order of a reaction = 1
